Works great for my spark 40
5 Stars
Works great for my spark 40
I use it to power my spark 40 guitar amp like others have stated. I use my amp in my simi truck as a Bluetooth speaker as well and this will power it all day for that then I'll play guitar after I'm done driving and it still has charge left. I'm going to get a second one to power my pedal board 😁. I use a USB to 9v converter for that.

1.0 out of 5 stars First Pack Bad - Replacement pack has very little capacity
Reviewed in the United States on January 13, 2022
I purchased this pack to allow portability of my Positive Grid Spark guitar amplifier. The first pack I received either had defective cell(s) or a defective charge/analyze circuit. All led’s of the 4 step led charge indicator would illuminate when the pack was charging, but only 2 or 3 would illuminate when the charger was disconnected from the pack, even after 5 days of charging. Amazon did send out a replacement pack immediately. The new pack displayed a 75% charge upon arrival, I was worried, but after a few hours of charge time all 4 led’s illuminated as expected. I haven’t used the Spark for more than 2 or 3 hours at a time but so far the battery pack has worked great and the portability aspect is great. I’ll update the 3 star rating in a few months after more testing and use. I’m always leery of “unusually named” crappy Chinese lithium battery products and their very optimistic rated vs. actual capacity. Lol
By the way, the magnetic phone mounts work great and far better than I expected as an option for mounting the battery.

One year later…Replacement pack does not fully charge and dies after adding only 20% charge to my iPhone 14 Pro Max.

I maybe have 15-20 hours of use with the Spark amp. Really disappointed. I’ll take it apart eventually and replace the cells.

Update….Who cares……This pack, yep #2, is an absolute POS. I’ve made multiple attempts to reach the seller!!!😂😂😂😂
Who am I kidding. Great idea, but super crappy execution. I look forward to a proper, tear down and analysis! Ordinarily wouldn’t take the time but I’m almost irritated enough to add it to the list of projects!
